Conditions which cause this to happen include: * A flush may have attempted to update or delete rows and an unexpected number of rows were matched during the UPDATE or DELETE statement. Note that when version_id_col is used, rows in UPDATE or DELETE statements are also matched against the current known version identifier. * A mapped object with version_id_col was refreshed, and the version number coming back from the database does not match that of the object itself. * A object is detached from its parent object, however the object was previously attached to a different parent identity which was garbage collected, and a decision cannot be made if the new parent was really the most recent "parent".

A refresh operation proceeds when an expired attribute is accessed on an object, or when :meth:`_query.Query.get` is used to retrieve an object which is, upon retrieval, detected as expired. A SELECT is emitted for the target row based on primary key; if no row is returned, this exception is raised. The true meaning of this exception is simply that no row exists for the primary key identifier associated with a persistent object. The row may have been deleted, or in some cases the primary key updated to a new value, outside of the ORM's management of the target object. rNcz|sd||z}tj||dS)NzDInstance '%s' has been deleted, or its row is otherwise not present.) state_strsa_excInvalidRequestErrorr#)r$r%stater's rr#zObjectDeletedError.__init__sJ 026..2G2GH  "++D#66666r c.|jd|jdffSr*r,r/s rr0zObjectDeletedError.__reduce__r1r r2r3r r rr:r:ks\&T,--777.-744444r r:ceZdZdZdS)UnmappedColumnErrorz5Mapping operation was requested on an unknown column.Nrr r rrBrBs????r rBceZdZdZdS) NoResultFoundz2A database result was required but none was found.Nrr r rrDrDs<<<r#rclsname_as_plain_name)r$applied_to_property_typerequesting_property applies_toactual_strategy_type strategy_keys rr#z LoaderStrategyException.__init__s '  & / /<rrrrr r:rBrDrFrHrr4r!r r rr`s!
